As the third installment in a series systematically searching dual active galactic nuclei (AGN) among merging galaxies, we present the results of 20 dual AGNs found by using the SDSS fiber spectra. To reduce the flux contamination from both the fiber aperture and seeing effects, the angular separation of two cores in our merging galaxy pairs sample is restricted at least larger than 3″. By careful analysis of the emission lines, 20 dual AGNs are identified from 61 merging galaxies with their…

The DEEP2 Galaxy Redshift Survey: AEGIS Observations of a Dual AGN at z = 0.7
We present evidence of a dual active galactic nucleus (AGN) within an early-type galaxy at z = 0.709 in the extended Groth strip. The galaxy lies on the red sequence, with absolute magnitude MB =
Buried AGNs in Advanced Mergers: Mid-infrared Color Selection as a Dual AGN Candidate Finder
A direct consequence of hierarchical galaxy formation is the existence of dual supermassive black holes, which may be preferentially triggered as active galactic nuclei (AGNs) during galaxy mergers.
Discovery of a dual active galactic nucleus with ∼8 kpc separation
Targeted searches for dual active galactic nuclei (AGN), with separations 1 -- 10 kpc, have yielded relatively few successes. A recent pilot survey by Satyapal et al. has demonstrated that
Two in one? A possible dual radio-emitting nucleus in the quasar SDSS J1425+3231
The radio-emitting quasar SDSS J1425+3231 (z = 0.478) was recently found to have double-peaked narrow [O III] optical emission lines. Based on the analysis of the optical spectrum, Peng et al.
A comprehensive classification of galaxies in the SDSS: How to tell true from fake AGN?
We use the W Hα versus [NII]/Hα (WHAN) diagram introduced by us in previous work to provide a comprehensive emission-line classification of Sloan Digital Sky Survey galaxies. This classification is
Was 49b: An Overmassive AGN in a Merging Dwarf Galaxy?
We present a combined morphological and X-ray analysis of Was 49, an isolated, dual-AGN system notable for the presence of a dominant AGN, Was 49b, in the disk of the primary galaxy, Was 49a, at a
Active Galactic Nuclei in the Sloan Digital Sky Survey. I. Sample Selection
We have compiled a large sample of low-redshift active galactic nuclei (AGNs) identified via their emission-line characteristics from the spectroscopic data of the Sloan Digital Sky Survey. Since
Emission lines in early-type galaxies: active nuclei or stars?
We selected 27 244 nearby, red, giant early-type galaxies (RGEs) from the Sloan Digital Sky Survey (SDSS). In a large fraction (53%) of their spectra the [O III]λ5007 emission line is detected, with
Very Long Baseline Array Imaging of Type-2 Seyferts with Double-peaked Narrow Emission Lines: Searches for Sub-kpc Dual AGNs and Jet-powered Outflows
This paper presents Very Long Baseline Array (VLBA) observations of 13 double-peaked [O iii] emission-line type-2 active galactic nuclei (AGNs) at redshifts 0.06 < z < 0.41 (with a median redshift of
The host galaxies of active galactic nuclei
We examine the properties of the host galaxies of 22 623 narrow-line active galactic nuclei (AGN) with 0.02 < z < 0.3 selected from a complete sample of 122 808 galaxies from the Sloan Digital Sky
